Thanks, Marc. The 0.8X wide angle adapter with a 24mm lens yields a
19.2mm. Used with a 21mm lens, the combo produces a 16.8mm lens.
With a 35mm, one derives a 28mm lens. Looking at a picture of the
adapter, I figure one loses 1/3 to 2/3 of a stop with the combo.
The 0.8X W/A converter might be an economic alternative to filling
one's bag with a slew of W/A lenses if the quality drop isn't too
significant.
